This is a critical study of the philosophy and political practice of the Czech dissident movement Charter 77. Aviezer Tucker examines how the political philosophy of Jan Patocka (1907-77), founder of Charter 77, influenced the thinking and political leadership of Vaclav Havel as dissident and president. It is a serious treatment of Havel as philospher and Patocka as a political thinker. Through the Charter 77 dissident movement in Czechoslovakia, opponents of communism based their civil struggle for human rights on philosophic foundations, and members of the Charter 77 movement later led the Velvet Revolution. After Patocka's self-sacrifice in 1977, Vaclav Havel emerged a strong philosophical and political force, and he continued to apply Patocka's philosophy in order to understand the human condition under communism and the meaning of dissidence. However, the political/philosophical orientation of the Charter 77 movement failed to provide President Havel with an adequate basis for comprehending and responding to the extraordinary political and economic problems of the postcommunist period. In his discussion of Havel's presidency and the eventual corruption of the Velvet Revolution, Tucker demonstrates that the weaknesses in Charter 77 members' understanding of modernity, which did not matter while they were dissidents, seriously harmed their ability to function in a modern democratic system. Within this context, Tucker also examines Havel's recent attempt to topple the democratic but corrupt government in 1997-1998.
